Classic Game Room season 1 - 5/20/2000. MDK2 for the Sega Dreamcast. What does MDK stand for? Well, watch the episode and find out. This first person shooter kind of game for the Dreamcast had a unique comic book style like the Watchmen mixed with anime references and science fiction. It was a lot of fun to play and looking back on it was an awesome game. For whatever reason this has not come out on the PS3, Wii or Xbox 360.
